Clutter rejection for MTI radar using a single antenna and a long integration time [PDF]

, 2011
Moving Target Indicators (MTI) are airborne radar systems designed to detect and track moving vehicles or aircrafts. In this paper, we address the problem of detecting hazardous collision targets to avoid them.

GLRT-Based Direction Detectors in Homogeneous Noise and Subspace Interference [PDF]

, 2007
In this paper, we derive and assess decision schemes to discriminate, resorting to an array of sensors, between the H0 hypothesis that data under test contain disturbance only (i.e., noise plus interference) and the H1 hypothesis that they also contain ...

A radar extended target angle estimation method based on effective phase clustering

The Journal of Engineering, 2023
For high‐resolution radar, traditional direction of arrival (DOA) angle measuring algorithms for point‐like targets cannot be directly applied to extended targets.

Symmetric sparse linear array for active imaging

, 2018
Sparse sensor arrays can achieve significantly more degrees of freedom than the number of elements by leveraging the co-array, a virtual structure that arises from the far field narrowband signal model.

Hyperparameter free sparse estimation for wideband multiple‐input‐multiple‐output radar direction finding without secondary data

IET Radar, Sonar & Navigation
The estimation of target directions of arrival (DOA) for wideband multiple‐input‐multiple‐output (MIMO) radar is investigated in this article. First, the authors establish a signal model for wideband MIMO radar systems.

High-Resolution Ultrasound Sensing for Robotics Using Dense Microphone Arrays

IEEE Access, 2020
State-of-the-art autonomous vehicles use all kinds of sensors based on light, such as a camera or LIDAR (Laser Imaging Detection And Ranging). These sensors tend to fail when exposed to airborne particles.
